Chastity and orgasm denial discussion

Background info: I’ve been in my cage for ten days now. As part of an anniversary “gift,” I asked my wife to keep me locked for a full month. It’s unusual for me to go more than ten days because either she feels sorry for me and lets me out, or she wants real penis so she lets me out. Both are great outcomes, but since it is her choice in both cases, I am happy with whatever happens. I worked out at the gym late and returned home when she was already in bed. After showering, I noticed she had left the key out, but I didn’t unlock because I hadn’t received permission yet. I joined her in bed, and she asked if I wanted to stay locked. I said yes, we spent some time together and I gave her oral. She definitely seemed to enjoy it. However, now I feel a bit guilty because I chose to remain locked. Previously, when I had the option but decided to stay locked, she would get upset or hurt, feeling that I didn’t want sex (which isn’t true). I do want sex, of course, but I also feel like I should be denied. It is certainly a challenge. I enjoy being caged up as long as it doesn’t cost her happiness. Are we the only ones facing this dilemma, or have other couples dealt with it? If so, how did you manage?
